Abstract
A ribbon lap unit contains support shafts for receiving and supporting a lap, a web transport means in the form of a web drafting mechanism, a web diverter, a diverter plate arrangement and a web collecting element. A web unrolled from the lap is fed through the web drafting mechanism and around the web diverter onto the diverter plate arrangement and thereafter onto the web collecting element. By means of the web diverter it is possible to arrange the diverter plate arrangement beneath the drafting mechanism. This, in turn, enables constructing a very compact machine.
